GRAND AVENUE, SANTA ANA, CALIFORNIA 1.0 INTRODUCTION This report provides the Remedial Action Plan (RAP) for the soil that is impacted by copper at the Former Circuit One (the Site) located at 2103 S. Grand Avenue, Santa Ana, California. The Site vicinity is shown on Figure 1. The Site location is shown on Figure 2. The purpose of this RAP is to summarize the environmental condition related to the copper contamination at the Site and to outline the proposed remediation activities. The RAP defines the contamination, remedial action objectives, remediation goals and the scope of the tasks that will be conducted to remediate the soil impacted by copper. The subsurface soil beneath the Former Circuit One Facility is impacted by volatile organic chemicals (VOCs), specifically, trichloroethene (TCE), and copper. There is no indication that the groundwater beneath the site is impacted by copper. These contaminants are believed to be from the former use of the Site for circuit board manufacturing. This RAP is prepared to addresses remediation of the soil impacted by copper. 2.0 BACKGROUND This section provides the site description, site history, site geology and hydrogeology ·and previous investigations and extent of contamination. 2.1 Site Description The Site is located at 2103 S. Grand Avenue in the City of Santa Ana, California (Figure 2). It is situated on the northerly parcel identified as Parcel 1 on the Record Survey dated May 1993 and recorded in Book 46, Page 22 of the Records of Survey of Orange County, and also shown on a Map filed in Book 65, page 37 of Records of Survey of Orange County. The site is a part of Assessor Parcel Number (APN) 014-173-05. A copy of the APN map is included in Appendix A. Industrial plaza has an area of approximate 9.3687 acres. As shown on Figure 2, there are 15 buildings in the plaza. The buildings are tilt-up construction. The plaza includes a number of suites that are used for storage, metal part manufacturing and many other commercial/industrial uses. 2.2 Site History The property that comprised the three parcels was acquired by North, Central and South, Inc. in May 1963 (GeoRemdiation, Inc. [GRI] 1992). Prior to this transaction, the land was used for agricultural purposes. The three separate legal parcels were acquired by Industrial Plaza LP from Warner Properties Inc., Warner Central Properties Inc. and Warner South Properties Inc. on May 17, 1971. By December 1963, construction of two buildings on the property at 2101-2115 S. Grand and 2117-2127 S. Grand had been completed. Between January 1964 and March 1970, a variety of general industrial uses occupied the Site. The premises at 2103 S. Grand and adjacent suites at 2101 and 2105 S. Grand were utilized for circuit board manufacturing from April 1970 to February 1990. The most recent occupant of 2103 S. Grand was Circuit One, a division of L.H. REMEDIATION SCIENCES 1 Former Circuit One 2103 S. Grand Avenue, Santa Ana, California Proiect No. 11-0106 Research, Inc. (GRI 1992). The Site at 2103 S. Grand has been vacant since abandonment by Circuit One in early 1990. There was a clarifier in suite 2103 that was used by Circuit One. The former location of the clarifier is shown on Figures 5 through 8. In the late 1980s, it was discovered that the condition of the clarifier had deteriorated (GRI 1992). It is believed that VOCs and copper entered the subsurface from this clarifier. Shallow copper contaminated soil was also found by RS in the southeastern portion of the Site in May 2012 and it is believed to be from the use of the area for storage (RS 2012B). The clarifier was removed in the early part of the project and reportedly some remedial excavation was conducted in the vicinity of the clarifier to remove some of the impacted soil. 2.3 Site Geology and Hydrogeology The following subsections describe the topography, geology, soil type, hydrologic setting and hydrogeologic setting of the study area. 2.3.1 Topography At the time of this study, the average elevation at Industrial Plaza ranged from approximately 65 feet above mean sea level (amsl) in the southwest to 68 feet amsl in the northeast (United States Department of Interior Geological Survey 1965). The topography in Industrial Plaza slopes very gently from the northeast to the southwest. 2.3.2 Geology and Soil Type The Site is located in the Santa Ana Valley-Capistrano Valley Province (California Department of Conservation Division of Mines and Geology 1976). The lowland strip separating the coastal hills from the Santa Ana Mountains includes the flood plain of the Santa Ana River in the northern segment and the Capistrano Valley in the southern segment. This area is comprised of a homoclinal sequence of mostly westerly-dipping rocks ranging in age from the Jurassic basement rocks on crest of the range Cretaceous and Tertiary formations exposed where the Santa Ana Mountains merge with the San Joaquin Hills. Lithologic features of soil in the general area are described as clayey sand with silty sand, sand, sandy silt and sandy clay strata (California Department of Conservation Division of Mines and Geology 1976). Locally, the Site lithology consists of fine grained soils that are mainly lean clay and silt inter-bedded with sandy soils that are mostly silty sand. 2.3.3 Hydrologic Settings The site is located within the Santa Ana River Basin (CRWQCB 1995). The boundary between the Los Angeles and Santa Ana Regions is the Los Angeles County line. Since the county line only approximates the hydrologic divide, part of the Pomona area drains into the Santa Ana Region, and, in Orange County, part of La Habra drains into the Los Angeles Region. The east- west alignment of the crest of the San Gabriel and San Bernardino Mountains separates the Santa Ana River basin from the Mojave Desert, which is part of the Lahontan Basin. In the south, the regional boundary divides the Santa Margarita River drainage area from that of the San Jacinto River, which normally terminates in Lake Elsinore. Near Corona, the Santa Ana River has cut through the Santa Ana Mountains and flows down onto the Orange County Coastal Plain. The Pacific Ocean Coast of the Santa Ana Region extends from just north of Laguna Beach up to Seal Beach and the Los Angeles County line. Other features of the coast include Newport Bay, Anaheim Bay-Huntington Harbor, and the major coastal wetlands areas associated with those bays. REMEDIATION SCIENCES 2 Former Circuit One 2103 S. Grand Avenue, Santa Ana, California Proiect No. 11-0106 The Santa Ana River Basin is comprised of two sub basins, Upper and Lower Santa Ana River Basins. The Site is located in the Lower Santa Ana River Basins. It contains six reservoirs, consisting of the Laguna, Lambert, Peters Canyon, Rattlesnake, Sand Canyon, and Siphon Reservoirs. There are two lakes located in this sub basin, Anaheim Lake and the Irvine Lake (Santiago Reservoir). According to the Water Quality Control Plan, groundwater at the site is of beneficial use. 2.3.4 Hydrogeologic Settings Orange County consists of an alluviated coastal plain occupying the north western part of the county and mountainous area extending to the Pacific Ocean in the south western portion of the county (California Department of Water Resource [CDWR], 1967). The site is located within the Coastal Plains of Orange County Basin (CDWR, updated 2003). The Orange County Groundwater Basin is located adjacent to the Pacific Ocean. It is found within the Lower Santa Ana River shed. Groundwater in this basin typically flows from the Santa Ana Mountains through the Irvine sub basin and out westerly into the Main Basin (DWR, 1967). Locally, the first groundwater is found in a thin groundwater bearing zone starting at about 20 feet below ground surface (bgs). In the shallow groundwater in the vicinity of the study area, the groundwater flow directions are affected by infiltration, pumping groundwater and absence of infiltration by pavements. The shallow groundwater flow in the area is typically to the southwest. 2.4 Previous Investigations and Extent Of Contamination Between December 1988 and August 2012 several investigations and some remedial activities were conducted at the Site and within Industrial Plaza. The investigations included the sampling of seventy soil borings including thirty two by RS, converting six of the soil borings to soil vapor extraction wells that were eventually not used due to tight soil conditions, converting three of the soil borings to dual air sparging wells that were not implemented for remediation purposes, converting fifteen of the soil borings to groundwater monitoring, conducting cone penetration testing (CPT) at eleven locations within Industrial Plaza. A groundwater pump and treat (P&T) system was installed within Industrial Plaza to treat groundwater that was extracted from some of the groundwater wells. The P&T operated from about 1992 to 2012. The P&T system was shut off in May 2012 and its operation was terminated in August 2012. TCE, some breakdown compounds of TCE and copper were found in the soil beneath the Site. The groundwater is impacted by similar VOCs and 1,4-dioxane but copper was not found in the groundwater above its reporting limit. Assessments conducted by RS have delineated the extent of TCE and copper impacted soil at the Site (RS 2012A and RS 2012B). In 2012, vapor intrusion risk evaluation (VIRE) was conducted for Suites 2103 and 2105 S. Grand Avenue (RS 2012C). Based upon the VIRE, it was determined that the estimated cancer risks from the VOCs affected subsurface are below the known cancer risk for the U.S. population and are considered acceptable under California Proposition 65. Similarly, the estimated Hazard Quotient is below the Hazard Index of 1.0, which is considered acceptable to the California Environmental Protection Agency. No significant cancer risks or health hazards were anticipated to occur as a result of worker exposure to chemicals detected in soil vapor under the two suites. In April 1990, nineteen (19) soil borings that ranged from 2 feet to 15 feet bgs were sampled at the Site and at 2105 S. Grand Avenue (GRI 1992). The locations of these borings are shown on Figure 3. Some individual soil samples, composite soil samples and concrete core samples REMEDIATION SCIENCES 3 Former Circuit One 2103 S. Grand Avenue, Santa Ana, California Proiect No. 11-0106 were analyzed for metals. The results of some metals total threshold limit concentration (TTLC) and/or soluble threshold limit concentration (STLC) testing conducted at that time are shown on Table 1 In July 1990, one composite concrete sample was analyzed for STLC. It appears that the concrete sample was from the five sampling locations shown in the southern part of unit 2105 S. Grand Avenue (Figure 3). The results of these samples are shown on Table 1. In October 1990, four soil samples collected from the sump and trench within the Site were analyzed for TTLC and/or STLC (GRI 1992). Sample B-1 was collected from the sump pit. Samples Comp-1, Comp-2 and Comp-3 were taken from the trench. The results of these samples are also shown in Table 1. Six of the wells were initially designated as B-1 through B-6 (GRI 1993). These wells were later designated MW-1, MW-3, P-2, P-5, MW-5 and MW-2, respectively. The locations of the wells are shown in Figure 4. As shown on Table 2, copper was not found in the groundwater samples that were collected in 1993. In November 2011, RS sampled 17 soil borings (SB-1 through SB-17) and soil samples from this borings were tested for VOCs and metals (RS 2012A). The location of the soil borings are shown on Figures 5 through 8. Soil samples from 2 and 5 feet each of this borings were tested for metals. Table 3 shows the results of the Title 22 metals testing. None of the metal concentrations exceed their TTLCs. Only two soil samples had copper that exceeded ten (10) times the STLCs for copper. The samples were SB-1-2' (1,000 milligrams per kilogram [mg/kg]) and SB-2-2' (1,400 mg/kg). Borings SB-1 and SB-2 are located near the former clarifier. The samples were analyzed for STLC and the results were 32 milligram per liter (mg/L) and 54 mg/L, respectively. In May 2012, twelve (12) five-foot soil borings (HA-1 to HA-12) were advanced by RS in suite 2103 to obtain soil samples for copper analyses (RS 2012B). The location of the soil borings are shown on Figures 5 through 8. Soil samples were collected at 1-foot intervals starting at 1- foot bgs to 5 feet bgs. The samples were analyzed for copper. None of the copper in the soil samples exceeded its TTLC of 2,500 mg/kg. However, some of the samples had STLC results greater than its STLC of 25 mg/L. At 1-foot, the area around borings HA-11 and HA-12 had copper above its STLC. At 2 feet, the soil around boring SB-1, SB-2, HA-11 and HA-12 has copper above its STLC. None of the soil samples collected at 3 and 5 feet contained copper at or greater than 10 times its STLC. Based upon the copper data obtained from the soil samples collected in suites 2101, 2103, 2105 S. Grand Avenue and the outdoor borings just south and north of the suites, it appears that the background copper concentration in this area is in the range of 19 mg/kg and 43 mg/kg. The copper in the 3 and 5-foot samples collected from borings SB-1 and HA-4 near the former clarifier are 130 and 150 mg/kg, respectively. This indicated that the copper released from the former clarifier had migrated at least to a depth of 5 feet bgs. RS in its report titled "May and June 2012 Site Assessment Report" that is dated September 4, 2012 indicated that groundwater samples collected by GRI in 1993 did not show that the groundwater in the area contained copper above its reporting limit and that copper released from the clarifier area did not appear to have entered the groundwater. In its letter dated September 19, 2012, the California Regional Water Quality Board - Santa Ana Region (CRWQB) indicated that the site conceptual model discussed in the RS report titled REMEDIATION SCIENCES 4 Former Circuit One 2103 S. Grand Avenue. Santa Ana. California Proiect No. 11-0106 "May and June 2012 Site Assessment Report" did not include an assessment of completed exposure pathways for copper which is known to be present as a soil contaminant at the Site. During a meeting with the CRWQB on October 9, 2012, the CRWQCB suggested collecting additional soil samples beneath the area where copper was found above its STLC. RS requested to obtain groundwater samples from wells MW-5 and P-6B and test the groundwater for copper in lieu of collecting soil samples to determine if there is groundwater contamination by copper in the study area. The CRWQB agreed to this suggestion. The wells were sampled on October 30, 2012 (RS 2012D). Copper was not detected above its minimum detection limit (MDL) in the groundwater samples collected from wells MW-5 and P- 68. Well P-68 is located near the former clarifier in Suite 2103 S. Grand Avenue. Well MW-5 is located downgradient of the former clarifier just outside the suite. RS has shown that there is some soil at the site with copper that exceeds its STLC. This RAP is prepared to describe the remediation of the soil with copper above its STLC. It is known that there is some copper in the soil at depths of 3 and 5 feet bgs in the vicinity of the former clarifier above what is believed to be its background concentration of between 19 mg/kg and 43 mg/kg. But the copper concentration in the soil is below 10 times its STLC which means it does not have a leaching potential. Copper was not found above its reporting limit in the groundwater samples collected in October 2012 by RS from wells P-6B and MW-5 and the groundwater samples collected in 1993 from wells MW-1, MW-3, P-2, P-5, MW-5 and MW-2 by GRI. This indicates that the copper exposure to groundwater on the site conceptual model is incomplete. RS does not believe that there is any threat to groundwater contamination by copper after the soil with copper STLC of 25 mg/L or higher is removed. The soil that exceeds copper STLC equal or above 25 mg/L are shown on Figures 5 and 6. 3.0 OBJECTIVES AND TECHNICAL APPROACH The objective of the remediation is to minimize the presence of copper that is in soil above its STLC. The soil with copper concentration above its STLC should be remediated to prevent its leaching into the groundwater and contaminating it. The most cost effective remediation method is by excavation and offsite disposal of the contaminated soil. The cleanup goal for copper impacted soil is its STLC which is 25 mg/L. The vertical extent of copper impacted soil that requires removal is between 2 and 3 feet bgs. 4.0 SCOPE OF WORK The following sections describe the scope of work for the remedial excavation: 4.1 Prefield Activities This task will consist of activities to be performed in preparation for fieldwork. Prefield activities to be conducted as part of this task include: • Prepare and submit this soil RAP to the CRWQCB for their review and approval • Update the site health and safety plan • Obtain appropriate permit • Screen subsurface for underground utilities • Notify underground service alert regarding excavation • Schedule subcontractor to perform the remedial excavation REMEDIATION SCIENCES 5 . Former Circuit One 2103 S. Grand Avenue, Santa Ana, California Proiect No. 11-0106 It is expected that the following permits may be required for excavation operations: • A grading and building permit from the City of Santa Ana. • An air district permit. Prior to commencing with excavation activities, Underground Service Alert (USA) will be contacted at least 48 hours in advance to identify the location of utilities that enter the Site. All proposed excavation areas will be clearly marked with white paint as required by USA. USA will contact all utility owners of record within the Site vicinity and notify them of the intent to excavate. All utility owners of record will be expected to clearly mark the position of their utilities on the ground surface throughout the designated area. 4.2 Remove Piping Related to Groundwater Pump and Treat System To access the soil that is required to removed, the piping at the Site related to the P&T system that has been terminated will be removed and the connections of these pipes to the wells will be capped. The excavation will be conducted near wells P-6B and W-1 and precaution will be taken no to damage the wells. Excavation near the wells will be conducted by hand 4.3 Remedial Excavation Under this plan the soil exceeding the copper STLC concentration of 25 mg/L will be removed from the Site by excavation. The excavation and soil handling will be conducted by a qualified, HAZWOPER-trained contractor using conventional earthwork equipment. The contractor will prepare its own Site Specific Health and Safety Plan (HASP), which will address identification of hazards, hazard mitigation, safe work practices and emergency response procedures for the project. The site-specific HASP needs be prepared to comply with 29 CFR 1910.120 and 8 CCR GISO 5192. The contractor will also have to adhere to the HASP prepared by RS. Conventional construction equipment, such as a front-end loader equipped with a backhoe, will be used to remove the soil that is required to be excavated. During the excavation the air will be monitored following air monitoring requirement discussed in the site health and safety plan. The following procedures will be followed to remove the excavated soil. • Access the soil by removing the concrete slab inside the suites. • Excavate the contaminated soil to a depth of about 2.5 feet which is the approximate extent of the soil with copper above its STLC. • Backfill the excavated trench with clean imported soil. • Repair the concrete slab by dowelling it to the existing concrete slab. The thickness and strength of the concrete will be equal or greater than the excising concrete slab. Approximately 1,072 cubic feet of soil will be excavated for this remediation. The excavated soil will be stockpiled in an area that will be cordoned off with temporary fencing in the rear of the suite along the driveway near the boundary of the property west of the existing P&T system compound. The stockpile area will be lined with plastic sheeting and covered daily using plastic sheeting when not actively being worked on and at the end of each workday. Sand bags will be placed in the perimeter of the temporary fence as silt control. The source of the clean backfill material, certification that the fill is clean, and supporting analytical data will be obtained from the excavation subcontractor and submitted to CRWQCB approximately five working days before beginning excavation activities at the site. The clean REMEDIATION SCIENCES 6 . Former Circuit One 2103 S. Grand Avenue, Santa Ana, California Proiect No. 11-0106 backfill material shall not contain chemicals above United States EPA Preliminary Remedial Goals. A geotechnical field technician will provide observation and testing services during backfill operations. The clean backfill material will be moisturized as needed by hose or water truck prior to placement, or else mixed as the fill material is being placed. Fill will typically be placed in 6-inch lifts and compacted. In situ density tests will be performed to determine when a minimum relative compaction rate of about 90 percent has been achieved relative to the maximum dry density of the soil. A compaction report will be submitted to the City of Santa Ana Building Department in accordance with the grading permit. During excavation activities, depending on soil conditions, there is potential to generate airborne dust. Dust control measures will comply with the local Air District feasible control measures to protect on-site and off-site receptors from chemicals in soil and nuisance dust.Dust suppression will be performed by lightly spraying or misting the work areas such as the excavation and soil handling areas with water. Misting may also be used on soil placed in the transport trucks. Efforts will be made to minimize the soil drop height from the excavator's bucket onto the soil pile or into the transport trucks. The excavator will be positioned so as to load or stockpile soil from the leeward side. After the soil is loaded into the transport trucks, the soil will be covered to prevent soil from spilling out of the truck during transport to the disposal facility. Additionally, soil stockpiles and truck beds containing soil will be covered to minimize the potential for dust generation. If precipitation is anticipated, engineering controls will be implemented to minimize the collection of rainwater in the soil stockpile area. While on the property, all vehicles will maintain slow speeds for safety purposes and for dust control measures. Before exiting the job site, the vehicle's tires will be inspected and brushed, if necessary, to ensure that impacted soil remains on-site. This cleanup/decontamination area will be established as close to the excavation and/or loading areas as possible to minimize spreading the impacted soil. 4.4 Confirmation Soil Sampling and Testing Four side wall and two bottom confirmation soil samples will be collected from each of the two excavation areas. The samples will be collected by using clean trowels. The soil will be transferred from the trowel into eight ounce jars that will be provided by an analytical laboratory. The samples will be labeled, logged on a chain of custody form and placed in a chilled ice chest for shipment to an analytical laboratory. Before each use, the sampling trowel will be cleaned in a solution of phosphate-free detergent and potable water followed by double rinsing with potable water. The samples will be sent to a State of California certified laboratory and tested for copper using EPA Method 6010B and for its STLC using EPA Method 6010B STLC Citrate. If the samples do not meet the cleanup goal, the excavation trench will be extended until the remaining soil has copper STLC less than 25 mg/L. 4.5 Waste Disposal of Contaminated Soil Off-site disposal will be conducted based on the soil stockpile analytical results under appropriate documentation and in accordance with applicable federal, state, and local regulations. REMEDIATION SCIENCES 7 Former Circuit One 2103 S. Grand Avenue, Santa Ana, California Proiect No. 11-0106 As a hazardous waste generator, Industrial Plaza will secure an EPA Identification Number from California Department of Toxic Substance Control (DTSC) for proper management of the hazardous waste. Compliance with the DTSC requirements of hazardous waste generation, temporary onsite storage, transportation and disposal is required. Any container used for onsite storage will be properly labeled with a hazardous waste label. Within 90 days after its generation, the hazardous waste will be transported offsite for disposal. Any shipment of hazardous wastes in California will be transported by a registered hazardous waste hauler under a uniform hazardous waste manifest. Land disposal restrictions will also be followed, as necessary. Any shipment of non-hazardous waste in California will be transported under a nonhazardous waste manifest or bill-of-lading. 4.6 Record Keeping The remediation contractor will be responsible for maintaining a field logbook, which will serve to document observations, personnel on site, equipment arrival and departure times, and other important project information. Logbook entries will be complete and accurate enough to permit reconstruction of field activities. Logbooks will be bound, with consecutively numbered pages and each page will indicate the date and time of the entry. All entries will be legible, written in black or blue ink, and signed by the author. Language will be factual and objective. If an error is made, corrections will be made by crossing a line through the error and entering the correct information. Corrections will be dated and initialed. Because some portion of the excavated soil likely will be profiled as hazardous waste under California or EPA regulations, the Uniform Hazardous Waste Manifest (hazardous waste manifest) form will be used to track the movement of soil from the point of generation to the point of ultimate disposition. The hazardous waste manifests will include the following information: • Name and address of the generator, transporter, and the destination facility • United States Department of Transportation description of the waste being transported and any associated hazards • Waste quantity • Name and phone number of a contact in case of an emergency • EPA Hazardous Waste Generator Number • Other information required either by the EPA and/or the DTSC. Any soil that is profiled as non-hazardous and sent off site for disposal will be documented using a Non-Hazardous Waste Manifest or Bill-of-Lading form. At a minimum, this form will include the following information: • Generator name and address • Transportation company • Accepting facility name and address • Waste shipping name and description • Quantity shipped. Prior to transporting the excavated soil off site, an authorized representative of IP will sign each hazardous and/or non-hazardous waste manifest. The removal action site manager will maintain one copy of all hazardous and/or non-hazardous waste manifests on site. REMEDIATION SCIENCES 8 Former Circuit One 2103 S. Grand Avenue, Santa Ana, California Proiect No. 11-0106 4.7 Report Preparation After completion of the soil excavation, a report summarizing the excavation procedures, documenting observations, and presenting the confirmation sampling will be prepared. The report at a minimum will include the following: • A summary of work completed • Description of field methods and observation • Waste disposal manifests • Laboratory reports • Tables • Figures showing excavation and confirmation samples area REMEDIATION SCIENCES 9 Former Circuit One 2103 S.
